Abstract

Valvola di spurgo automatica (34) per spurgare aria da un serbatoio di liquido pressurizzato, che comprende un pistone (4) in una camera del pistone (25) disposta in un canale di flusso che proviene dal serbatoio. in un passaggio del pistone (24) attraverso il pistone (4) è ricavato un primo orifizio (6), ed il pistone (4) viene spinto in direzione a monte da una molla elastica (8), un secondo orifizio (16) viene disposto nel canale di flusso. Quando il gas viene espulso dal serbatoio, la molla elastica (8) tratterrà il pistone (4) in una zona di equilibrio, permettendo al gas di essere scaricato dal serbatoio attraverso il canale di flusso. Quando il liquido inizia a fluire attraverso il canale di flusso, il differenziale di pressione sopra il pistone (4) aumenta, per cui il pistone (4) si sposta contro una sede (23) di una valvola a fungo (5) e chiude il canale di flusso ed il serbatoio idraulico.Automatic purge valve (34) to purge air from a pressurized liquid tank, which includes a piston (4) in a piston chamber (25) arranged in a flow channel that comes from the tank. in a passage of the piston (24) through the piston (4) a first orifice (6) is obtained, and the piston (4) is pushed upstream by an elastic spring (8), a second orifice (16) is placed in the flow channel. When the gas is expelled from the tank, the elastic spring (8) will hold the piston (4) in an equilibrium zone, allowing the gas to be discharged from the tank through the flow channel. When the liquid begins to flow through the flow channel, the pressure differential above the piston (4) increases, whereby the piston (4) moves against a seat (23) of a mushroom valve (5) and closes the flow channel and the hydraulic tank.
